INSOLE FOR BOOTS OR SHOES.

SPECIPCATION forming part of Letters Patent No. 371,657, dated October 18, 1887.

Application filed October 20, 1886. Serial No. 216,697. (No model.)

To all 10.71.0711, t may concern.-

Beit known that we, GEORGE D. ADAMs, of Newburyport, and WILLIAM L. BARRELL, of Lawrence, both in the county of Essex and State of Massachusetts, have invented a new and Improved Inner Sole for Boots or Shoes, of which the following is a specification.

Our invention relates to inner soles for boots or shoes; and it consists in certain new and useful constructions and combinations of the several parts thereof, substantially as hereinafter described and claimed.

In the drawings, Figure l is a face View' of an inner sole constructed according to our invention. Fig. 2 is a side elevation of ashoe with a portion of its side broken away to show the method of using our inner sole in it. Fig. 3 is an enlarged view of a portion of the upper face of our inner sole, showing the weaving of the fabric on that side. Fig. 4 is an enlarged view ofa portion of the lower face of our inner sole, or the face which is placed downward in the shoe, showing the weaving of the fabric on that side. Fig. 5 is a vertical section through the piece of fabric, showing the weaving which connects its two parts or faces together. Fig. 6 is a transverse section on line y g/ of the part of the fabric on the side shown iu face View in Fig. 8. Fig. 7' is a transverse section on line 0c .fr of the part of ghe fabric on the side shown in face view in S is the inner sole of the shoe, which is made to combine the necessary stiffness and durability throughout its thickness and the necessary softness and pliability upon the face thereof with which the foot comes in contact in the shoe, in the following manner: l

The fabric of which the sole is composed is woven double, or two-ply, one ply ofwhich, A, is formed of very heavy and coarse hardtwisted cotton threadssuch as is commonly known as cotton duckN-while the other ply, B, is formed of fine and soft threads. The two plies A and B are united by one of the fine and soft threads b of the ply B, being carried into the ply A and around its threads at intervals, as shown, in the weaving of the fabric. This method of weaving prevents any of the coarse and harsh threads of ply A from weave fabrics of two or more plies for clothing and household and other furnishing; but none of these have possessed the necessary stiffness in one ply to form the inner soles of shoes, combined with the requisite softness and pliability in the other to protect the foot from the harsher ply, both because not woven with that end in view and chieiiy because they are not made of fibers of that stiffness and solidity when woven to produce these effects. This is because the combination of these characteristics to the necessary extent in our fabric renders it quite useless for clothing or furnishing purposes.

When the fabric is woven as described, the inner sole is eut out of it of proper shape, as shown in Fig. l, and is saturated with a sizingliquid to prevent the threads from raveling or puiling apart and the plies from being separated. The sizing-liquid may be used to saturate the fabric, however, before the sole is cut out of it. After being thus properly sized and dried, the inner sole is inserted into the shoe and sewed therein in the usual manner, as shown in Fig. 2.

It will be observed that no pressure or strain of the foot upon the upper ply, B, ofthe sole, even when the latter is saturated/with heat and moisture, as is often the case, will materially disturb the relations of the two plies A and B of the sole; nor will such pressure, heat, and moisture destroy the stiffness of the lower ply, A, since these qualities come from the coarse and hard twist of its threads in the weaving. lt will further be observed that this method of uniting the plies together to form an inner shoe-sole takes the strain of the foot off the fastenings by which the sole is securedto theinsideof the shoe, and renders the shoe more durable, since the connection between the plies eases the strain upon the lower one.

IOO

ner sole for boots or shoes, formed of more than one ply, the ply on one side being Woven from coarse hard-twisted threads adapted to give the necessary stiffness, and the ply on the other side or face being Woven from finer and softer threads, and said plies being united together by threads b b, and the sole being saturated with size adapted to prevent said plies from raveling and separating, substantially as described.
